Pma1p is an abundant 100 kDa protein with 10 membrane-embedded domains (reviewed in 9 and 10). Its abundance, combined with its function as a prominent housekeeping gene, has led to its use as a marker for stress, secretion, and plasma membrane biogenesis (11 and reviewed in 12).

Pma1p is highly regulated by glucose, both transcriptionally and postranslationally (13). The presence of glucose induces a 2- to 4-fold increase in PMA1 expression, mediated by the transcription factors Rap1p and Gcr1p (14, 15). Glucose also triggers a rapid 5- to 10-fold increase in ATPase catalytic activity via Ptk2p-mediated phosphorylation of a serine residue in the Pma1p C-terminus (13, 16, 17). In contrast, phosphorylation of Pma1p by serine/threonine kinase (Yck1p and Yck2p), in the presence of glucose, is correlated with decreased proton pump activity (18). Glucose addition induces a Pma1p conformational change that is correlated with enzyme activity; moreover, glucose disrupts complexes between acetylated tubulin (Tub1p, Tub2p, and Tub3p) and Pma1p that are known to inhibit H+-ATPase activity (19 and references contained therein, 20). Finally, PMA1 transcription may be regulated by the cell cycle as its promoter is also a binding site for the transcription factor Mcm1p (21).

Pma1p homologs have been identified in A. thaliana and other fungi such as C. albicans and S. pombe (22, 23, 24). Additionally, H+-ATPase homologs in pathogenic fungi are being studied as targets for antifungal reagents (25 and reviewed in 26).", "date_edited": "2006-04-27"}, "literature_overview": {"primary_count": 279, "additional_count": 308, "review_count": 99, "go_count": 12, "phenotype_count": 10, "disease_count": 0, "interaction_count": 148, "regulation_count": 13, "ptm_count": 18, "funComplement_count": 0, "htp_count": 23, "total_count": 827}, "disease_overview": {"manual_disease_terms": [], "htp_disease_terms": [], "computational_annotation_count": 0, "date_last_reviewed": null}, "ecnumbers": [{"display_name": "7.1.2.1", "link": "/ecnumber/EC:7.1.2.1"}], "URS_ID": null, "main_strain": "S288C", "genetic_position": -2.0, "regulation_overview": {"regulator_count": 25, "target_count": 0}, "reference_mapping": {"592214": 1, "576647": 2, "615179": 3, "610722": 4, "416907": 5, "418282": 6, "362735": 7, "362207": 8, "644981": 9, "590599": 10, "524494": 11, "560753": 12, "576653": 13, "617452": 14, "631775": 15, "523996": 16, "592151": 17, "635631": 18, "525395": 19, "526367": 20, "615897": 21, "576567": 22, "615312": 23, "576662": 24, "576573": 25, "576588": 26, "648276": 27}, "history": [{"category": "Name", "history_type": "LSP", "note": "Name: KTI10", "date_created": "2010-02-16", "references": [{"id": 648276, "display_name": "Butler AR, et al.

Expression

Expression data are derived from records contained in the Gene Expression Omnibus (GEO), and are first log2 transformed and normalized. Referenced datasets may contain one or more condition(s), and as a result there may be a greater number of conditions than datasets represented in a single clickable histogram bar. The histogram division at 0.0 separates the down-regulated (green) conditions and datasets from those that are up-regulated (red).
